COMMUNICATIONS SYSTEM
Procedural Steps (Cont):
8. Cut a piece of telephone cable long enough to reach from the radio to the desired
height of the antenna.
9. Strip the insulation from one end of the two cable wires. Untwist the wires enough
to splice one wire to a bare section of the radiating element and the other wire to a
bare section of the reflectors.
10. Toss the suspension rope or wire over the limb of a tree, and pull the antenna up to
the desired height.
11. Strip insulation from the other end of the two-wire cable. Untwist and connect one
wire to a screw on the radio (ground) and the other wire to the center of the radio
antenna connector.
12. If communications are not satisfactory, reverse the connections at the radio.
Record the BDAR action taken. When the mission is completed, as soon as practicable,
repair vehicle using standard maintenance procedures.
